*sigh*. Now I feel stupid.
I had never enabled ohci at cardbus, because I didn't have any ohci
controllers.
Or so I thought.
In fact, the ehci controller probes "companion controllers" - which are ohci
devices!
With this crucial change, I can now probe the cardbus USB2 card just fine.
Unfortunately, it doesn't *work* with USB 1.1 devices. The device is handed
over to the "ohci" controller, which then announces "device disappeared after
reset", and the port is dead thereafter until I pop the card out and plug it
back in.
However, I can probably work around that with a USB2 hub.
